Simple solution for silent power and solar. Running my camp trailer off of this Delta 3 Ultra Plus... have it stored under my dinette bench and running my 30a trailer plug directly to it. This allows all the functions of my trailer when traveling and without hook ups or running my generator. Having this unit on board has allowed me to swap out my inefficient small propane fridge for a residential 120v mini fridge and run power to it constantly even when traveling. Using basic functions like fridge, Led lights, 12v diesel heater and some TV usage, and brew a few coffee pods, I've gone a full weekend using only about 75% of the charge. I can fire up my generator, set the charge limit to 600-800w to keep the generator idled down low and quiet, top unit off in an hour or two and be good to go again for another day or two.... I used to run my generator nonstop for very small electrical needs, this has eliminated the need for that. I also purchased a 400w Renogy solar blanket and have ran a solar cable to the electrical port on the side of the trailer. Looking forward to trying this out as summer approaches to keep this topped off and possibly eliminate the need for my gas generator altogether.... I know I could have went with a hard mounted solar set up with house batteries, but for the cost and plug and play convenience, as well as the option to pull this out and use it in the house or elsewhere, this just made more sense for me.

Wouldn't you know it. We haven't had an outage since we put it into service. I do like it. There is peace of mind knowing that we have a secondary power source.

My first Power Station was the EcoFlow River 2 Max. It’s a reliable unit I use everywhere, from camping, remote work, and even an extended hospital stay where outlets were out of reach. Then I stepped up to the Delta 3 Ultra Plus. As a renter, this is the real solution I needed for home. Unable to use a gas generator, or install something permanent, this was the perfect unit. During a series of storms that resulted in intermittent power outages over several days, this powers everything from my home office equipment, the refrigerator, and even the entertainment system. It gives instant access to power whenever we need it, runs quiet, and is very dependable. Recharges quickly as well.

So far really like the unit, just need ecoflow to either release the adapter to add 2 expansion batteries, or quit the false advertising claiming it can have 2 expansion batteries connected at same time.

I recently purchased this unit to replace a 20 year old gas generator after realizing what a pain it was to deal with the old unit outside in a snow storm! I have not had the opportunity to use the Ecoflow too much but, it certainly seems to offer what I needed for a back up to power outages. It is heavy yet, easily portable with an extendable handle and built in wheels. Fits in a closet. Since it was delivered on a very cold day the unit had to get to room temp before it could be charged. It is recommended that the unit be partially discharged occasionally to maintain the battery. I have powered numerous small appliances at a time and the reserve power hardly diminishes. I'll update as it is used more often.
